To all whom it may concern:

Be it knownthat I, FREDERICK W. COLE, a

.citizen of the United State residing at Newton, county.-of-Middlesex, btatc ofMassachusetts, have invented certain new and useful Improvements in Automatic Non-Interfering Repeaters for Fire-Alarm Circuits, of which the following is a specification.

, The present invention relates to automatic repeaters for fire-alarm circuits wherein a plurality of street-circuits each comprising boxes and signals and a street-magnet are employed and which repeat the signal receivedfrom one circuit over all of the other circuits and actuate the signal devices in such circuits and may also actuate additional signal devices on separate circuits.

The object I have in view is the production of a device which may receive a signal from a street-circuit and repeat the signal to other street-circuits without danger of interruption from other signals sent over any of the circuits over which the signal is being repeated even though two or more signals be started at the same instant of time and without the signal in control being interrupted or mutilated. In other words, my object is the production of a repeater which will have all of the attributes of the 'most-highly organized street-signal boxes and which will not only absolutely prevent interference, but which will not mutilate the signalreceived;

Another object is to produce a device which will cut out the street-circuit over which a signal is bein sent when such signal is locked out, so that t e locked-out signal will be sent er its own street-circuit and actuate the signal devices therein, the signal in control repeating its signal to all of theother streetcircuits except the one cut out.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the necessary parts ol a device embodying my invention. Fig. 2 is a diagrammatic view showing the several circuits. Fig. 2*" is a diagrammatic view showing the parts at rest and waiting the reception of a signal. Figs. 3, 4, and 5 are views of a modification showing, respectively, the parts in the normal position, the parts while locked out, and the parts while in control. Figs. ti, '7, and h are views of an other modlllt'niion similar to the three preceding Iigures. l igs. ti, It), and It present still :lllul-llel mmliliention. Figs. l2, l3, and

14 are similar views of another modification. Figs. 15, 16, and 17 are similar views of another modification. Fig. 18 is a view show.- ing a modification in which additional magnets are employed as substitutes for mechanical devices. Figs. 19 to 22 represent the moving elements of a modification based upon the structure disclosed in my Patent No. 616,222, but with my present improvements applied.

In all of the several views like parts are designated by the same reference characters.

The structure illustrated in Figs. 1 and 2 is based upon that disclosed in the patent to Francis A. Skelton, No. 569,250, dated December 2S, 1897, but with my present improvements added.

In Fig. 1, l and 2 represent the street-magnets, each of which forms a portion of a strect circuit embracing a number of callboxes and signaling devices, the circuits being normallyclosed. I t is to be understood that as many street 'magncts are employed as there are strcet+circuits. The number added, however, will not change the principle of the device. The armatures 3 3 are carried on levers 4, pivoted to the frame (not shown) and retracted by springs 5-whcn the magnets are dcenergized and they are not otherwise prevented. These armatures and levers constitute moving devices. Each moving device has two positions, a normal. or attracted position and an abnormal or retracted position, the first when the magnet is energized or the member locked out, as will 'be explained, and :the second when the magnet is dcenergized and its armature is free to be retracted. 6 is the rcscttings'haft, carrying a series of levers 7, provided with adjusting-screws 7 as shown, for engaging with the levers 4 and resetting all of the moving devices which may be in the retracted position should their strcctcircuits be broken or for any other reason. To the resetting-shaft 6 is secured an arm 8, which, through a link 9, is connected to a lever 10, which is, provided with a pin 11, which in turn will engage with an otlset in the free extremity of an arm 12, carried upon the shaft-13. The shaft 13 may be rotated by clockwork of the customary type, (indicated generally by the character 14,) which constitutes a repeating-train and wluch comprises a train of gears and a drum and cord and weight, the latter two not bcing'illus-- trated. The end of thelever 12 engaging with the pin 11 will serve as a lock to prevent the shaft 13 from rotating. Should the lever be elevated a sufficient distance to cause the pin 11 to clear the ofiset end of the lever 12, the'shaft 13 will be revolved by the repeating-train. The lever 10 is provided with an upward-extending portion which is provided with a small friction-roller 15, which is adapted to engage with a cam 16, carried by the shaft 13. cam is such that when the lever 12 is in engagement with the pin 11 the lever 10 may be elevated a sufiicient distance to disengage the pin from the lever before the roller is stopped by engagement with the cam 16. U on the shaft 13 and cam 16 revolving the ro ler 15, engaging with the latter, will be- .with additiona brushes 19*, forming a or tion of additional signal-circuits 19', inc uding signal devices 19", if such are desired. The locking shaft 20-carries a plurality of angle-levers 21, supported upon eccentrics 22 above and in front of each moving member. These angle-levers constitute means for controlling the lock out levers, as will be described, and each has three positions-win,

first, an elevated position before a signal isreceived and after a sufficient interval of time has elapsed after the receipt of a signal; second, a lowered retracted position, and, third, a lowered attracted position, the two last positions being assumed durin the receipt of a signalv The locking-shaft 1s adapted to be given a half-revolution by means of a locking-train (shown generally at 23) and provided with the usual cord and weight. (Not shown.) The movements of the lockin -train are controlled by a timing-train.

(S iown generally at 24.) This timing-train has connected to it by a friction-coupling a' timing-lever 25, provided at its free extremity with a roller which engages with a cam 26, secured to and revolved by the shaft 13. This timing-lever is provided with a releasing-sector 27, having a notch by which the relatively short and long extremities of the double lever 28 may be engaged and permit the locking-shaft 20 to alternately make about a half-revolution. Each of the anglelevers 21 is provided with a recess 29, which is caused to engage when permitted by means of a counterweight 30 with a spring 30, carried by the free extremity of the locking-1ever 31. This extremity of the locking-lever The configuration of the is formed with a hook 32, which engageswith a similar hook 33 made upon the moving member. The locking levers constitute means for locking the moving members in the normal or attracted position The locking-levers 31 are counterbalanced and are depressed at the proper moment upon each op eration of the repeating mechanism by means of levers 31*, carried upon the second resetting-shaft 34. This second resetting-shaft is oscillated by means of an arm 35, connect ed to a lever 36, which is provided with a rolleradapted to engage with a cam 37, carried upon the shaft 13. Above each streetmagnet is a cut-out lever 38, which is normally elevated by a spring (not shown) to engage with the fixed contact 39, thus constituting a switch or cut-out. The contact and lever are connected so as to form a portion ofthe street-circuit. The free end of the lever is provided with a cam-shaped ex tension 40, which may be engaged by a pin 41, carried by the angle-lever 21. 42 is a shaft mounted above and parallel to the resetting-shaft 6 and carrying fingers 43, which are adapted to reset the indices 44 when such are released.

So much of the device described is quite similar to that disclosed in the Skelton patent above referred to.

The mechanismso far described will preventinterference by si nals received after the ap aratus has receive and is repeating a sig-, na It will not, however, prevent interference by signals received simultaneously. Such signals will all be received and re eated with unintelligible results. The addltional mechanism by means of which the desirable andinew results are secured is as follows; Mounted adjacent to each moving device is a lever 45, which is preferably pivoted to the shaft 42, a block 46 surrounding the shaft and provided with a notch which will prevent .endwise movement of the lever 45 and will also limit, if desired, the extent of its oscillatory movement, the extent of movement being determined by the length of the slot. Each lever is provided with an extended portion 47 having a flat upper surface and a notch 48. It is also rovided with a depending portion 49 and a ateral extension 50, the

latter constituting a counterweight portion. Each angle-lever is provided at its lower extremity with a pin 51, which may bear upon the extension 47 or rest within the notch 48, as de ends upon the position ofthe parts. Each ever 7 of the resetting device is provided with a pin 52, which may engage with the downward projection 49. The lever 45, togcther with the ins and notches, constitutes a means for hol ing the angle-lever in the retracted position.

The operation of the device is as follows: The street-ma nets 1, 2, 1, and 2* being each in a normally c osed street-circuit their armatures 3 3 will be attracted, as shown in Fig. 2*. As soon as a signal (which is composed of alternate makes and breaks of the circuit) is .sent it will be received by the magnet in the circuit, which magnet will be dcenergized and its armature retracted by means of its spring 5 This retracting motion will oscillate the shaft 6 through the lever '7,raise the link 9 and lever 10, causing the pin 11 to slip by the end of the lever 12 and permitting the shaft 13 to make a revolution by means of its train of gears. This will rotate the cylinder 17 and pass the plates 18 under the brushes 19, thus completing and then breaking all of the street-circuits except the one over which thesignal is being received, which circuit will not be interfered with, as the cutout in that circuit will not be opened, the operation of which will be described subsequently. As the shaft 13 rotates the roller 15, engaging with the cam'16, will lower the lever 10, oscillate the resetting-shaft, and return the armature to position in front of its magnet. The pin 11 will engage with the lever 12 and prevent further rotation of the shaft 13 until the magnet is again deener gized, when thesame operation will occur. Upon the shaft 13 revolvim thecam' 26 engaging with the lever 25 will move it, so that the arm 28, engaging with the notch in the releasingsector 27, will permit the lockingtrain 23 to impart approximately a'half-re'volution to the locking-shaft 20. This will depress the angle-lever 21 by means ofthe cam 22. This movement, it will be understood, takes place immediately upon the rotation of the shaft 13 and. before it has rotated to any considerable extent. The retraction of the lever 7 will, by means of the pin 52 engagingwith the depending portion 49 of each of the levers 15, oscillate them upon their axis. The angle-lever 21 will be moved backward by its engagement with the lever at as the latter is retracted and permit the pin 51 to drop in the notch 48. This lever 45 will only be moved so as to have its notch 4Sout 01'' the path of engagement of the pin 51 when the lever 7 is in its farthest retracted position, and the lever 7 in returning to normal will allow the notch 18 to come far enough upward ,to engage the pm 51 before the lever 21 has swung forward far enough. to get it out of the range of said notch. 'lhcrelbrc the said lever 21 will always be held from swinging entirely forward when actuated by or following an operating moving device The parts will then be in the position shown at A in Fig. 2. At the same time the moving devices o'l'rall oi the other streetanagnets will bein the restored position. Their levers 15 will be oscillated in a manner similar to that ol' the magnet over which the signal is being sent; but as theirangle-levers 21 will not be oscillated, but simply depressed by the action of their eccentrics 22, theirpins '51 will continue ously-locked-out moving devices.

to rest upon the extensions 47 of the levers -15. .In this position the notch 29 will engage with the spring on the locking-lever 31, depressing it to cause its-hook 32 to engage with the hook 33 on the armaturc-hwcr 14, and thus lock out the moving member. At the same time the pin 41 will engage with the lever 38 and separate it from contact with the part 39, at this point brei king the street-circuit. The parts cooperating with such locked-out moving member will be in the position shown at C in Fig. 2 and will leave the device over which the signal was originally received in control, with its street-circuit at 38 and 39 closed. The parts will work in this manner during the time the signal is bemg received and repeated as many tunes as provided for by the street box. After the signal is completed atime will elapse until the timing-train moves the lever 25 against the base of the cam 26, permitting the arm 28 to passthrough the notch in the releasingsector and rotating the locking-shaft 20 the balance of its revolution. T his'will, through the agency of the eccentrics 22, elevate all of the angle-levers 21 to the position shown at A in Fig. ,2, thus unlocking all of the previ- The apparatus will be then in position to receive and repeat another signal. Should two signals be received at about the same instant of time on difl'erent circuits, they will actuate their own street-magnets, all other street-magmas having their moving devices locked out as previously described, and the signal will be repeated over the circuit of such locked-out magnets. The two magnets in control will actuate their moving devices together so long as they move in unison. As soon, lnnvever,

as the moving device oi one magnet is rein unison will have their angle-levers 21 held away l'rom their lock-(nit levers 31 by engagement of their pins 51 with the notch 18. They will be moved, as ])i'(\"i ll$l described, into these notches 48 by the retraction of their armature-lcvers r, which, as previmisly described, will cngag(.=\viththe lower extremities of the angle-levers 21.. As soon, however, as one oi" thesc armattire-levers l ceases to be retracted it will l'ail to move out its angle-lever. The lever 15 will, however, be oscillated by the lever 7 in. retracting, thereby releasing the pin 51 from the noichlh, and thus allowing the angle-levcr 21 to swing forward until the shoulder in its notch 21) passes over the spring 30 on the lever. 31, which is depressed at this time bylcver 31, which acts at each operation oi the repeater to thereby lock said lever in such position thereafter so that its moving device will be locked "1" of its signals.

out and will not respond to the impulses of its magnet thereafter. To make the operation more .clear, the simultaneous receipt of two signals, as shown in Fig. 2, maybe des('1ibed. At B the moving member of the .box is shown as arranged for sending the signal 3-2, the box D. to send the signal 2-1-2. Should both boxes be sprung simultaneously or nearly simultaneously, the corresponding street-magnets will be deenergized, the mechanism actuated, and the inactive or energized magnets locked out, as at C, breaking their circuits and allowing the first impulse of the tivo signals, which are identical, to be repeated over such locked-out circuits. The second impulse of the two signals will be sent under exactly similar conditions. When the box at B is sending its third impulse, the box at D will be at the position to produce the pause or rest between the 2 and the Consequently that circuit will be broken. Its armature, however, will be returned to the inactive position (shown at A) I y means of its lever-7, and its lock-out lever 31 will be depressed at the proper moment by means of its lever 31? engaging with the moving devices and preventmg its retraction when the lever 7 1s again re- The third impulse of the signal at,

cnit is again completed .to send the 1 of its signal the moving device cannot respond, because it is engaged by the lock-out lever 53 t, which. cannot rise owing to the pressure of the angle-lever 21. The magnet will remain locked out until after the completion of the revolution of the shaft 20, which can occur only after a .suitable interval has elapsed after the last impulse of the signal at Bv has been received. It is to be noted that the angle-lever at l) is swung in after it has been lowered by the rotation of the shaft 26,-

Consequently the street-circuit at D will not be cut out and the signal from B will notbe repeat- The signal atl) will be contin over any other circuits, as its. street-magnet will be locked out. It will be understood,

therefore, that when .a signal is locked out should a plurality of signals bereceived at the same time such signal will not be muti- This will release the pin 51- lat ed, but will be continued to be sent over its own circuit, while the magnet in control will repeat its own signal over the circuits which are primarily locked out and will of course actuate the signal apparatuses in its own circuit.

My invention may be modified inmany ways. In Fig. 3 the'lever 45 is provided wit a finger 53, which may engage against a cor responding finger 54, carried by the angle-lever 21 and lock out the moving member 4 by engagement therewith, as shown in Fig. 4.

an arm 58, secured to the shaft 20, so that the angle-lever may be elevated under some conditions without affectin the position of the arm 58. The lock-out evice comprises the lever 21 and a short pivoted lever 59, connected by a link to a lever 61, secured to the shaft 6, and which may be a portion of thelever 7 As shown in Fig. 7, the lever 59 being oscillated by the retractionof any armature will en a e with the bottom end 56 and lift the ang e-. ever21 so that it can swing into position to lock the lever 31, thus locking out-the moving member 4 of any circuits which operated simultaneous and have ceased to so operate. In Fig. 8 acircuit is shown 4 in control. The angle lever- 21 is swung back by the moving device 4 in retracting and cannot swing forward to locking position of Fig. 7 when said moving'deviee is restored, as the lever 7 in restoring also turns the short lever 59 into normal position, which thereby allows the lever 21 to drop the length of its slot 57, and thus bring its locking-shoulder below the end of the lever 31 as it swings toward said lever.

Fig. 6 shows the parts in their normal position. .Sho'uld two or more magnets receive a signal simultaneously, then the moving device'swill continue to move so long as they move in unison. As soon as they cease to so move, then the firstone to reac 1 g the retracted position will lock out all the others in the attractedposition by the engagemer'it 'of the lever 59, with the bottom portion 56 of the angle-lever of such magnet, thereby lifting the same from dotted-line position in Fig. 7, so as to enable it to swing to the full-line position there shown.

In Figs. 9, 10,. and 11 a somewhat-different structure is shown. In this View in lieu of the an le-lever a horizontal lever 62 is provided,I1aving anangular' offset 63 at. its free extremity. This lever 62 is so pivoted in re cut-out device already describedv that shown move in unison.

lation to the armature-lever 4 and th releasing-lever 7 that it may rest upon the latter signal and will complete its revolution after a definite time has elapsed after the signal has I been received. In operation an armaturelever 4 being retracted, as shown in Fig. 11,

by the deinagnetizing of its magnet will engage with its lever 7- and oscillate the shaft 6, retracting all of the other levers 7 and allowing their levers 62 to drop to the position shown in Fig. 10. The ofl'set of the levers 62 will then engage with the levers 4 and serveas a means for locking them out. Should two moving devices be actuated at the same time, they-will be free to move so long as they v Should, however, one be attracted while the other is still retracted, the lever 7 being also retracted at such time will allow the lever 62 to drop, thus locking'out. the lever 4 first-attracted. Instead of the in these fi ures may be employed. The part 65 is fixer, while 66 may drop down to the position shown inFig. ill and be supported by the lever 62, breaking contact when the device is cut out. A dog 66", adapted to be engaged by thc'cam 64*, serves as a means for returning any moving member of which its street-circuit should be accidentally broken and also restores the levers 62 to normal po sition after the completion of-a signal.

The modification shown in Figs. 12,13, and 14 employs a lever 68 III lieu of an eccentric on the lock-out shaft 20 and a cam-shalt 69,

' which is geared to and rotated once at each impulse of the repeating mechanism. This cam-shaft carries a double gibboi'is cam 71),

which will engage with the lock-out lever 31 and depress it, so that its hooked extremity I can engage with the lever 4 to hold it in normal or restored position.

The lever 21- can hold this lever 31 in its locking position to lock out all the moving members not in control. It will'be noted that the double gibbouscam 7() has one end longer than the other and its shaft is revolved simultaneously with'the mstoration of the lever 7, as it geared to the revolving shaft that restores tion of the parts.

when it depresses lever 31 to its'greatest eX-.

tent and low enough to allow the lever 21 to swing forward and lock it, which lever 31 will do for every operating-lever that has started In unison and has ceased to so operate. Fig.

shows the normal posi 1.4 shows the operating-lever in control. It has been restored-by the lever 7, and just as it is so restored the short end-of the cam will have depressed the lever 31 enough to catch and hold said lever, but not far enough to allow the lever 21 to swing forward to its lockingposition. The lever 31 will thereafter be held in this locking position by the friction-of the operating-lever pressing against it; but when this pressure is taken oil by the attraction of the magnet then said lever, being counterbalanced in the usual way, will be free to and will swing upward, allowing free passage-way for the operating-lever to be again retracted 0n the next break in its I circuit. i

' In the modification illustrated inFigs. 15, 16, and 17 instead of the shaft and cam a shaft 71 is employed and is rotated at each impulse in the same way. This shaft actu ates a bell-crank lever 72 by means of a crank 73 and link 74. The two extremities of the bell-crank alternately engage with the lockout lever and spring on the end of it in a similar manner to the double cam 70. In Fig. 18 the same idea is carried out with'lock-out magnets instead of mechanical devices. This device is somewhat similar to that disclosed in the patent to W. H. Kirnan, No.749,387, dated J anuary 12, 1904. In these views 77 and 7 7 are the non-i nt erferenee m agnets connected in a local circuit 78,'wh.ich includes a battery 79 and a magnet 80 for actuating the starting llltC-lHtHlhlll. This circuit also includes cut: outs S1 81, actuated by the mm'ing'members 4 4 Adjacent each moving device 4 is an armature S2, attracted by theolocleout magnets 77 and 77, and when dropped passes within the range of movement of the moving device 4, as shown in broken lines at magnet 77, preventing retraction of thelatter. A restoring-sln1ft S3,- actuated by the timingtrain and earlying a cam 84, moves the armadevice 4 is retracted, as shown, at the magout 81* and actuating the. starting device by means of the magnet 80. This will deenergi'zc the cut-out,magnet 77 and allow its armature 82 to drop out of the vmagnetic field.

and assume the position shown inbroken lines at 7 7 and lock all the moving devices and break the line-circuit at 82. It will, however, not drop beyond the held. of magnetic attraction of the active non-interferenee magnet 77 ol the strect-n-iagnet, but will be supported upon its moving member, keeping the line-circuit closed at 82 On the magnet being again energized its moving device 4 will be attracted, the circuit 78 comln operation whenthe street-magnet is deenergized the moving ture 82 within the attractive scope of its net 77, breaki ng the loeal'circui't 78 at the cutleted, and the armature 82 attracted, as the ocal circuit 78 will be closed at 81 before 82 is released. Should a'street-magnet remain energized, its moving device 4 will not be re- 5 tracted. This will permit its correspondingnon-interference armature 82 to drop to the dotted-line position shown, thus looking out the street-magnet. Should two magnets start in unison, the onewhich is first in the retracted position thereafter will break the local circuit 78 and allow the non-interference armature '82 of the other to drop, as shown in broken lines, thus locking out that moving device. The non-interference armar 5 tures are returned by means of the restoringcam 84.

In Figs. 19, 20, 21, and 22 are shown my idea as applied to a device similar to that shown. in my Patent No. 616,222, dated De- :0 cember 20, 1898. In this case the lock-out device 86 is normally held (see Fig. 19) by the moving device 87, which in retractive position allows said lock-out device to immediately drop, (see Fig. 20,) and all such devices 2 5 that do not drop will be immediately picked up by a cain 88 on the revolving shaft 89 (see.

Fig. 21) and moved to engage with the abut ment 90 and lock their respective armatures from operating. The lock-out device or de- 0 vices which first move are thereafter alternately held in a second position (see Fig. bythe releasing-lever 91 and their respective moving devices 87-. If two moving devices are operated simultaneously in the begin- 3 5 ning, thefirst one thereafter to-bein attracted position out of unison with the other will immediately get locked out 'by a further move ment of its locking-out device, as shown in the ,dotted-lineposition in Fig. 21. After these locking devices have been locked out they cannot be a ain restored-until after the end of the signal by camshaft 89 completing its revolution when released by time-train. In Fig. 22 the releasing-lever 91 is placed 5'within'the opening in the moving device insteadof above, as' shown in Figs. 19, 20, and 21..
